Tool Setup on UniLegs™
1 Lay out rails L as shown with screw tracks facing up. Insert the hex head portion of screw D into each track (see Detail G). With bracket K facing downward, align holes (indicated by arrows), with hex head threads and lower into place. Tighten bracket snugly against rails with locknuts H.
 2. From opposite end of rails, again insert the hex head portion of screw D into each track. Align holes in bracket J with hex screw threads and lower into place. Install locknuts H. Square up assembly and tighten all fasteners. Ensure all hole locations match those in drawing before proceeding. 3. Position a UniLeg™ at each end of rail assembly with the extended brackets facing the same direction as the leg flares (see Side View). Align rail flanges with retainer nooks on top of UniLegs™ and slide into place. Note: Ask for help holding UniLegs™ apart during this step if needed.
Caution: To prevent the tool from tipping during use, always ensure the extended portion of the bracket is facing the same direction as the leg flare (see Step 3 above). Always situate tool on level ground.
4. To finish installing the rail assembly, loosen each T knob and extend latch plates up and over rail flange (see detail). Tighten T knobs snugly in place. Check T knobs often and tighten as needed. 5. Insert a hex screw D through the outward hole of the extended portion of the bracket K. Start a knob F several threads onto the hex screw D and leave loose for now. Repeat same procedure on opposite side of rail assembly. 6. Align slotted brackets on underside of tool to outside of extended brackets K and J. Align slots with hex screw threads and slide in place to a complete stop. Tighten knobs F snugly. Install handles referring to Steps 8 & 9 above.
